TO (1127/ wi'mm it may concern:

Be it known that I, ISIDOR KITSEE, of the city and countyofPhiladelphiafitate of Pennsylvania, have invci ted certain new andusefullmprovementsin VirelessorSpaceTeleg- Buoys, as is well known, areplaced at loca-, trons which are considered dangerous for'sea-' going.vessels, and it has been the aim to provide such buoys with devices withthe aid of which their presence should be'knownto ves sels passingnearby, so that they may beable to avoid the danger. heknowledge of thelocation of these buoys is of the greatest 2o importance for vessels infoggy or stormy weather, and so far no device is in existence capable ofwarning the passing vessels of their presence. To produce such a deviceis the aim of inyinvention. Referring to the drawings, Figure 1 is aside elevation of the buoy; Fig. 2, a diagrammatic view showing theelectrical connection of my device partially inclosed in and partiallyout of the buoy.

A is the buoy p oper; B, the mast secured to the buoy, having securedthereto the sphere b.

O is a tube secured to thebottom of the buoy, provided with theanchor-cable eye 0. D is a carbon plate; E, a zinc plate. Connected tothe carbon plate D through the wire 5 is one te'rminalbf theelectrolytic interrupter consisting of the platinum Wire II, providedwith the insulation 1 and the con- 40 ducting-tube C. The other terminalof the I interrupter is connectedthrough the wire 6 with the brush j,which brush is in electrical connectionwith the drum 5, the periphery ofwhich consists of metallic points alternating with insulated spaces. Onthis drum rests the brush j, connected through wire 3 with the primar Pof an inductorium. The other terminal 0 the primary is connected throughwire ewith the zinc plate E. In proximity .to the primary P is thesecondary S, one terminal of which is connected through wire 2 with theground or watcrG, the other terminal through wire 1 with the aerialconductor 1). The plates DE fulfil the office of electrodes of a voltaiccell, and-tho salt water of the ocean or seafnlfils the ofiice of theelectrolyte of such cell. If a carbon plate and a zinc plate areimmersed in sea-water,the voltage developed is about one andfive-tenths, and each square inch exposed will give, ifthc 6o two-platesare not too far apart, aboutthreeeighths of one'ampere, and as the waterof the sea is always in motion polarization will be obviated. Theworking of the electrolytic interrupter is to-day so well: known that itdoes not need further explanation.

The plates D E are secured to the buoy in such manner that the greatestpart of these plates is exposed to the waves of the ocean, and theelectrolytic interrupter is also to its greatest part im mersed in thewater, and,with the exception of the aerial conductor, all other partsare inclosed in the buoy. Through the immersion of the zinc and carbonplates an electric current is generated. This current passes through theprimary coil, wire 3, brush 7, metallic contact-point of the drum J,brush 3'', wire 6, electrode H of the electrolytic interrupter, throughthe water to electrode O, and through wire?) and plate D and water as anelectrolyte back to the plate E,

The drum- J may be actuated by any of the well-known means,eitherniechanicahthrongh a clockwork, or electricalwith the aid of a motor.On. the periphery of the drum are, as stated before, conducting contactpoints. They are grouped in such manner as to .represent the prearrangednumber which should correspond to the numberof the buoy placed on thechart. It is understood that the contact-points are ll electricalconnection with the conducting-drum.

The working of the device is as follows: The genera ed-straight currentis made an interrupted one with the aidof the electrolytic interrupterand will therefore induce impulses in the secondary. Theseimpulses, ifof high enough potential, will, with the aid of the aerial conductor, betransmitted to obj jects, such as vessels, and translated into sound orrecord if these vessels are provided with a suitable receiver for thesecurrent .im

pulses or waves but these interrupted or re-' curring impulses can onlyflow to the primary it both of the brushes jj are in electrical contactwith each other, and as this electrical contact is only possiblewhen-the brush j strikes one of the contact-points on the periphery ofthe drum it-is obvious that the transmitted electric impulses will be inaccordance with the grouping of these contact-points, and as thesecontact-points represent the number of the buoy it is obvious that thetransmitted electric i-mpulses'when translated into sound, glow, orrecord will 'intheir grou ping also represent the number of the buoyfrom which the-impulses are transmitted. I

I have in the drawings illustrated the device t as beingprovidedwith-bne voltaic couple im mersed in the sea-waterlo'generatethe necessarycurrent; butif itis' found that the potential of thecurrent is too low for practical purposes other voltaic cells, primaryor secondar maybe substituted for'thevc0uple,'as described. Ihave alsoillustrated in thedrawin gs an electrolytic interrupter; but any otherof the well-known mechanical or electromagnetic devices may besubstituted.- So, for inrstance,ican the terminals of the wires or 6,

. no'w'connected to the electrolytic interrupter,

be connected to brushes of a mechanical interrupter revolving on thesame shaft as the.

drum J revolves. l v I Having now described my inventiomwhat "I claimasnew, and desire to secure by Letters. Pate t 1 t to 1 1.
